Underground Utilities

Underground electrical distribution and related utility work — primary and secondary feeders, transformer and switchgear foundations, and utility tie-ins.

What We Provide

Underground Utilities — in detail

Primary and secondary feeders, transformer pads, and utility tie-ins — here is how we put electrical distribution in the ground and coordinate it with TEP and Trico.

Primary & Secondary Distribution

  • Primary underground distribution — We install the medium-voltage primary that feeds pad-mounted transformers and switchgear across a site or campus, coordinated with the serving utility.
  • Secondary feeders and services — From the transformer to the building we install the secondary feeders and services that bring usable power to the gear.
  • Transformer and switchgear foundations — We set the pads, grounding grids, and stub-ups that pad-mounted transformers and switchgear sit on.

Utility Tie-Ins & Crossings

  • Utility tie-ins — We coordinate and make the connections to the serving utility's system, on their schedule and to their standards.
  • Wet-utility coordination — We coordinate water, sewer, and storm crossings with the electrical and communication pathways so separations and clearances meet code.
  • Grounding grids and systems — We install the grounding grids and systems that keep underground equipment safe and code-compliant.

Self-Performed

  • One crew, trench to terminations — Because we self-perform the trenching, the duct bank, and the electrical, the underground utility scope stays with one accountable team.
  • Sequenced with the building — We sequence the underground with the building schedule so power is where it needs to be, when it needs to be there.

Where It Applies

Markets we serve

From Tucson, our underground utility work serves commercial developments, industrial facilities, and municipal projects on TEP and Trico systems.

  • Site and campus power
  • Commercial developments
  • Industrial facilities
  • Municipal and public
  • Mixed-use

The Design-Build Advantage

Designed, self-performed, and accountable

We dig, install, and terminate — one contract from the trench to the gear. That keeps utility coordination, inspections, and backfill on a single schedule, with no sub waiting on a sub.

Back to Underground
  • Primary and secondary self-performed end to end
  • Utility coordination handled in-house
  • Trenching, duct bank, and wire by one team
  • Sequenced with the overall project schedule
